help

I don't know, it could be just my jumpers... anyways... I hooked up my C drive into this POS 98 system so I could copy off my files that I want... after setting the jumpers of it to "slave" (hopefully) and put it in, boot up the computer and I don't see it on there... how could I get it to show on here?? or it just doesn't like NTFS formated harddrive to show up?? should I check the jumpers?? is there a file I could edit that well show it??
